"The construction of a multi-threshold foil for fast neutron flux measurements is investigated. The factors governing the selection of the materials are the energy response of the given reactor, the half-life of the daughter, the prominent gamma ray emitted during decays, the power level of the reactor, the availability of adequate cross section data, and the alloying properties of the composite foil. A ternary system was chosen as a compromise between the difficulty of fabrication and the amount of information gained from one foil. The particular system chosen was In- P- Fe. The threshold reactions of these elements are In¹¹⁵ (n,n')115m at 0.40 Mev , P³¹ (n,p) Si³¹ at 2. 40 Mev, Fe⁵⁴(n, p) Mn⁵⁴ at 4.30 Mev, and Fe⁵⁶ (n,p) Mn⁵⁶ at 5.00 Mev. This foil is used to illustrate the feasibility of the construction of a multi-threshold foil by using it to make preliminary measurements of the fast flux"--Abstract, page ii.
